I HAVE A 94 E320 I HAVE REPLACED THE AIR &
FUEL FILTER, REPLACED THE SPARK PLUGS AND
I STILL HAVE A MISS. SOMETIMES AN OCCASIONAL
BACKFIRE SOUND WHEN I CAR IS WARMED UP
AND I DROP SPEED TO IDLE. I HAVE HAD DEALER
CHECK IT SEVERAL TIMES. (HE REPLACE THE
MOTOR MOUNTS THE FIRST TIME, BUT COULDN'T
FIND THE ACTUAL CAUSE OF THE MISS.
